CPU Boards - performance comparison

Please find below some performance comparison we've done for a set of most popular mini cpu-boards evaluated for OGN receivers.
In our tests we used sysbench in different configurations.

Please note the results are ordered from most-performant (left) to least performant (right).

Notes

Following commands were used to test the board:

1 Thread:  sysbench --num-threads=1 --test=cpu --cpu-max-prime=2000 run
2 Threads: sysbench --num-threads=2 --test=cpu --cpu-max-prime=2000 run
4 Threads: sysbench --num-threads=4 --test=cpu --cpu-max-prime=2000 run
256M: sysbench --test=memory --memory-block-size=1M --memory-total-size=256M run
512M: sysbench --test=memory --memory-block-size=1M --memory-total-size=512M run

Conclusions

For new installations it is strongly recommend investing in multi-core (at least 2 cores) hardware, as single-core mini boards may have problems dealing with intensive traffic. If in addition to OGN receiver software you plan to run other software on the same hardware (e.g. you are active feeder of ADS-B data to FR24), then definitely do not consider any single-core solution.

If, however, you already have one or you can get one really cheap - for now we recommend to go for Raspberry Pi! because of two main reasons:

  1. there is a very convenient installation procedure available for R. Pi (thanks to Mell's image)
  2. OGN receiver software is able to use GPU on Raspberry Pi (and that significantly improves performance, although e.g. BeagleBone Black without the use of GPU proves to offer similar performance as Pi with GPU)
